Temperature and Compass Display
Press the on/off button, located to the far left, briey
to turn the compass/temperature display on or off.
If the display reads CAL, the compass needs to
be calibrated. For more information, see “Compass
Calibration” following.
To adjust between Fahrenheit and Celsius, do the
following:
1. Press and hold the on/off button for
approximately four seconds until either a
ashing F or C appears.
2. Press the button again to change the display
to the desired unit of measurement. After
approximately four seconds of inactivity,
the new unit will be locked in and the
compass/temperature display will return.
If an abnormal temperature reading is displayed
for an extended period of time, please see
your GM dealer. Under certain circumstances, a
delay in updating the temperature is normal.
Automatic Dimming Mirror Operation
The automatic dimming mirror function is turned on
automatically each time the ignition is started.
To operate the automatic dimming mirror, do the
following:
1. Make sure the green indicator light, located to
the left of the on/off button, is lit. If it is not,
press and hold the on/off button for
approximately six seconds until the green light
comes on, indicating that the mirror is in
automatic dimming mode.
2. Turn off the automatic dimming mirror function
by pressing and holding the on/off button for
approximately six seconds, until the green
indicator light turns off.
Compass Calibration
The compass may need calibration if one of the
following occurs:
After approximately ve seconds, the display
does not show a compass heading, N for
North, for example, there may be a strong
magnetic eld interfering with the compass.
Such interference may be caused by a
magnetic antenna mount, magnetic note pad
holder, or a similar magnetic item.

The compass does not display the correct
heading and the compass zone variance
is set correctly.
In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed,
push the on/off button for approximately
12 seconds or until CAL is displayed.
The compass can be calibrated by driving the
vehicle in circles at 5 mph (8 km/h) or less until the
display reads a direction.
Compass Variance
The mirror is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if the
vehicle is outside of zone eight. Under certain
circumstances, as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. Compass variance is the
difference between earth’s magnetic north and true
geographic north. If not adjusted to account for
compass variance, the compass could give
false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance
zone number on the following zone map.2. Press and hold the on/off button untilaZand
a zone number appears in the display. The
compass is now in zone mode.
3. Keep pressing the on/off button until the
desired zone number appears in the display.
Release the button. After approximately
four seconds of inactivity, the new zone
number will be locked in and the compass/
temperature display will return.

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to time out or quit after several seconds
of transmission. This may not be long enough
for Universal Home Remote to pick up the signal
during programming. Similarly, some U.S. gate
operators are manufactured to time out in
the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator or garage door
opener by using the “Programming Universal
Home Remote” procedures, regardless of where
you live, replace Step 3 under “Programming
Universal Home Remote” with the following:
Continue to press and hold the Universal Home
Remote button while you press and release every
two seconds (cycle) the hand-held transmitter
button until the frequency signal has been
successfully accepted by the Universal Home
Remote. The Universal Home Remote indicator
light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming
Universal Home Remote” to complete.
Using Universal Home Remote
Press and hold the appropriate Universal Home
Remote button for at least half of a second.
The indicator light will come on while the signal is
being transmitted.
Erasing Universal Home Remote
Buttons
To erase programming from the three Universal
Home Remote buttons do the following:
1. Press and hold down the two outside buttons
until the indicator light begins to ash, after
20 seconds. Do not hold the two outside
buttons for longer than 30 seconds.
2. Release both buttons.
The Universal Home Remote is now in the training
(learning) mode and can be programmed at any
time beginning with Step 2 under “Programming
Universal Home Remote” shown earlier in
this section.
Individual buttons cannot be erased, but they can
be reprogrammed. See “Reprogramming a
Single Universal Home Remote Button” following
this section.

Turn and Lane-Change Signals
The turn signal has two upward (for right) and
two downward (for left) positions. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is nished, the lever will
return automatically.
To signal a lane change, raise or lower the lever
for less than one second until the arrow starts
to ash. This will cause the turn signals to
automatically ash three times. It will ash
six times if tow-haul mode is active. Holding the
turn signal lever for more than one second
will cause the turn signals to ash until you release
the lever. The lever will return by itself when it is
released.
An arrow on the
instrument panel cluster
will ash in the
direction of the turn or
lane change.As you signal a turn or a lane change, if the
arrows ash more quickly than normal, a signal
bulb may be burned out and other drivers will not
see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when
you signal a turn, check for burned-out bulbs and a
blown fuse. SeeFuses and Circuit Breakers on
page 540.
Turn Signal On Chime
If your turn signal is left on for more than
3/4 of a mile (1.2 km), a chime will sound at
each ash of the turn signal and the message
TURN SIGNAL ON will also appear in the DIC.
To turn the chime and message off, move the turn
signal lever to the off position.

N(Delay):You can set the wiper speed for a
long or short delay between wiping cycles.
This can be very useful in light rain or snow.
Turn the band to choose the delay time. The closer
to the top of the lever, the shorter the delay.
6(Low Speed):For steady wiping at low
speed, turn the band away from you to the
rst solid band past the delay settings.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band
to off.
Rainsense™ II Wipers
If your vehicle has Rainsense™ II windshield
wipers, the moisture sensor is located next to the
inside rearview mirror and is mounted on the
windshield. When active, these wipers are able to
detect moisture on the windshield and
automatically turn on the wipers.To turn on the Rainsense™ feature, the wipers
must be set to one of the ve delay settings on the
multifunction lever. Each of the ve settings
adjusts the sensitivity of the rainsensor.
Since different drivers have different setting
preferences, it is recommended that the mid-range
setting (position 3) be used initially. For more
wipes, select the higher settings; for fewer wipes,
select the lower settings located closer to the
off position on the multifunction lever.
The rainsensor will automatically control the
frequency of the wipes from off to high speed
according to the weather conditions. The wipers
can be left in a rainsense mode even when it is not
raining.
When Rainsense™ II is active, the headlamps will
turn on automatically after approximately 8 wipes.
The headlamps will turn off if the wiper switch is set
to the delay position, and there have been no wipes
for approximately 3 minutes or it has become light
enough outside. If it is dark outside, the headlamps
will remain on.
Notice:Going through an automatic car wash
with the wipers on can damage them. Turn
the wipers off when going through an
automatic car wash.

Climate Controls
Climate Control System
With this system you can control the heating,
cooling, defrost, defog and ventilation of your
vehicle.
Manual Operation
Turn the right knob clockwise or counterclockwise
to direct the airow inside of your vehicle.To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets and to the oor outlets.
The ow can be divided between vent and oor
outlets depending upon where the knob is placed
between the settings. A little air is directed towards
the windshield and side window outlets. Cooler air
is directed to the upper outlets and warmer air to
the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets, with some of the air directed
to the windshield, side window outlets, and
second row oor outlets. In this mode, the system
will automatically select outside air. Recirculation
cannot be selected when in Floor Mode.
The right knob can also be used to select defog or
defrost mode. For more information, see
“Defogging and Defrosting” later in this section.
By positioning the right knob between two modes,
a combination of those two modes is selected.
The air conditioning compressor will be on unless
the outside temperature is close to freezing.

Automatic Operation
AUTO (Automatic):When automatic operation
is active the system will control the inside
temperature, the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will
change to show the current temperature(s)
and AUTO will be lit on the display. The current
delivery mode and fan speed will also be
displayed for approximately 5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over
about 40°F (4°C). The air inlet will normally be
set to outside air. If it’s hot outside, the air
inlet may automatically switch to recirculate
inside air to help quickly cool down your
vehicle. The light on the button will illuminate
in recirculation.2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a
74°F (23°C) temperature setting and allow
about 20 minutes for the system to regulate.
Use the driver’s or passenger’s temperature
buttons to adjust the temperature setting as
necessary. If you choose the temperature
setting of 60°F (15°C), the system will remain at
the maximum cooling setting. If you choose the
temperature setting of 90°F (32°C), the system
will remain at the maximum heat setting.
Choosing either maximum setting will not cause
the vehicle to heat or cool any faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield.
This sensor regulates air temperature based
on sun load and also turns on your headlamps.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm air
is available. The length of delay depends on
the engine coolant temperature. Pressing the fan
switch will override this delay and change the
fan to a selected speed.

)(Bi-Level):This mode directs half of the air
to the instrument panel outlets and to the oor
outlets. The ow can be divided between vent and
oor outlets depending upon where the knob is
placed between the settings. A little air is directed
towards the windshield and side window outlets.
Cooler air is directed to the upper outlets and
warmer air to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets, with some of the air directed
to the windshield, side window outlets, and
second row oor outlets. In this mode, the system
will automatically select outside air.
-(Defog):See “Defogging and Defrosting” later
in this section.
@(Recirculation):Press this button to turn
the recirculation mode on. When the button
is pressed, an indicator light will come on.
This mode keeps outside air from entering the
vehicle. It can be used to reduce outside air and
prevent odors from entering your vehicle.
Recirculation may also help cool the air inside
your vehicle more quickly once the temperature
inside the vehicle is less than the outside
temperature.
The recirculation mode cannot be used with oor,
defrost, or defogging modes. If you try to select
recirculation in one of those modes, the indicator
will ash three times and turn off. The air
conditioning compressor will also come on when
this mode is activated. While in recirculation mode
the windows may fog when the weather is cold
and damp. To clear the fog, select either the defog
or defrost mode and increase the fan speed.
Recirculation mode can be turned off by pressing
the button again, or turning off the engine.
